#' Compositional data of histone marks in different regions of genome along with
#'  background information
#' A list containing two matrices storing composition of 5 histone marks
#'  (H3K4ME1, H3K4ME2, H3K4ME3, H3AC, H4AC)
#' in 5 regions of the genome
#' @format A list with 2 matrices - each with 5 rows (histone marks) and 
#' 5 columns (regions of genome). One is the
#' actual matrix (mat), the other is the background matrix (bgmat)
